Try the screen on another computer and observe the results. If the Screen works well on another computer then that means that there is a problem with the VGA of the first computer. But if you still have the same results, then the LCD has a problem, and try to work it out this way
Get to the menu of the LCD and select Auto adjustment...this will try to bring the resolutions to its default factory settings.
If your running Windows XP: right-click on the desktop, and select "properties" In the properties go to the screen resolution and try to change the resolution to a higher one and observe the results
If you are running Windows 7, right-click on the desktop and go to "personalize" and the locate "display" on your left side, at the bottom and this is where you can adjust your resolution. I hope this will solve your problem
The easiest thing to try is change the screen resolution before connecting via HDMI. The process is a little different depending on what operating system you're using.
For Windows Vista/Windows 7:
1. Right click on your desktop and select "Screen Resolution"
2. Slide the bar to change the resolution to either 1024x768 or 1280x1024.
3. Click apply.
For Windows XP:
1. Right click on your desktop and select "Properties"
2. Click on the tab to the far right that says "Settings"
3. Under Screen Resolution, slide the bar to change the resolution to either 1024x768 or 1280x1024.
4. Click apply.
Either of these resolutions should at least give you picture when you reconnect with HDMI. Once you get a picture, repeat these steps and gradually move the slider higher to get a better resolution picture. If you receive the incompatible signal message again, just wait 15 seconds and the previous setting will be restored.
If this doesn't work, you may also have to adjust the screen refresh rate. From the same window that has the screen resolution adjustment bar, click the link or button that says "Advanced." The second tab, "Monitor," has a drop-down menu to adjust the screen refresh rate. Depending on your HDTV, the most common setting for this could be 60 Hz, 70 Hz, or 120 Hz. If none of those values work for you, you should check the manual that came with your TV to check what the proper resolution and refresh rate should be for your computer connection.
Did you hook up your monitor directly to your video cards' visual port (whether it's VGA, DVI or HDMI) ? Did you make sure the driver you downloaded are compatible with your graphics card ? with your operating system ?
Frankly, I don't have any more suggestion than looking in your graphics card's manual to check troubleshoots. They might give you an idea.
One more thing, if you time ahead of you, you might want to check if your motherboard is compatible with your graphics cards. To do that you might want to pay a visit to the almighty Google.
Nvidia 9300GS is a well-performing graphics card. Such display resolution problems should not occur. To resolve issues of faulty display, download and install the latest driver of your Graphics Card. Go to Nvidia's official website and get your device's WHQL Version of driver, don't go for the Beta drivers.
It looks like your graphics card changes the screen resolutions and/or refresh-rate to something beyond your monitor's capabilities.
After installing the drivers and the screen goes black, restart you're computer and press F8 to get the Windows advanced menu boot and choose "Enable VGA Mode".
When booted into Windows, right click on the desktop and select "properties", select the tab "Settings" and pick a really low resolution like "1024x768" and press the "Apply" button (but don't reboot yet when asked to). Next press the "Advanced" button, then select the tab "monitor" and change the monitor resolution to "default" or 60Hz.
Now restart your system and see wether Windows will boot normally. If so, you can change the resolution and refresh-rate back to you preferred values. Whenever you pick a too high resolution or refreshrate the screen will turn black again, but don't worry, don't press anything and just wait 15s, after which Windows will roll back to the previous setting ...
why don't you go with the lower resolution itself as it was before. if you are not able to set the screen resoultion to lower what you can do is reset ur system.
press F8 key continuesly untill you get advanced boot system.
There you select "safe mode" and run the system.
Once it is booted try changing the resolution.
After getting the Advanced boot system you can also try by selecting "Last Known good Config......" so that it sets the old screen resolution...!
1. Download this driver.
2. Go to the Control Panel, Programs and uninstall the current nvidia driver.
3. Shut down computer.
4. Remove video card and re-install it.
5. Start computer and install new nvidia driver.
It is possible that you are playing the game at a higher resolution than your video card can support. Even if your computer is capable of displaying a high resolution during normal browsing activity, that doesn't mean it can support the same resolution during graphics-intensive use. Try turning down the resolution and the quality in your game options and see if the problem goes away. I ran into this same issue when trying to power a 1920x1200 monitor with a GeForce FX 5200 Ultra and discovered the solution is either a lower resolution or more graphics power.
